PCT/EP2007/052127, filed on Mar. 7, 2007. This application also

BACKGROUND OF THE INVENTION
[0002] The invention relates to a solid, textile and/or skin care
composition as well as to its use and manufacture. The invention
also relates to a laundry detergent or cleaning agent that
comprises the solid, textile and/or skin care composition.
[0003] Repeated washing of textiles often causes them to become
stiff and to lose their softness. In order to restore their
softness/flexibility, to lend them a pleasant fragrance and/or to
improve their antistatic properties, the textiles, after the actual
washing and cleaning process, are treated with a fabric softener in
a subsequent rinse process.
[0004] The majority of the commercial fabric softeners are aqueous
formulations that comprise a cationic fabric-softening compound
having one or two long chain alkyl groups in a molecule as the
major active ingredient. Widely used cationic textile-softening
compounds include for example
methyl-N-(2-hydroxyethyl)-N,N-di(tallowacyloxyethyl)ammonium
compounds,
methyl-N-(2-hydroxyethyl)-N,N-di(tallowacyloxyethyl)ammonium
compounds or N,N-dimethyl-N,N-di(tallowacyloxyethyl)ammonium
compounds.
[0005] Due to the cationic, textile softening compounds, these
conventional fabric softener formulations cannot be used at the
same time with the laundry detergent or cleaning agent in the
actual washing or cleaning process, because the cationic textile
softening compounds interact undesirably with the anionic
surfactants of the laundry detergent or cleaning agent. Therefore
an additional rinse process is required, which however is time and
energy intensive.
[0006] A further disadvantage of the conventional fabric softeners
is that they do not prevent lime scale residues being deposited on
the washing during the rinse step. In addition, the conventional
fabric softeners often leave behind unsightly deposits in the
dispensing draw of the washing machine.
[0007] Problems can also occur with other textile and/or skin care
compounds, which for example need to be dosed separately and/or
need a separate rinse cycle.
DESCRIPTION OF THE INVENTION
[0008] Accordingly, an object of the present invention is to
provide a textile and/or skin care composition that can be employed
together with laundry detergents or cleaning agents.
[0009] This object is achieved by means of a solid, textile and/or
skin care composition comprising a water-soluble carrier, a
textile-softening clay and a textile or skin care compound.
[0010] Such a textile and/or skin care composition can be used in
the main wash cycle of an automatic washing or cleaning process.
The textile and/or skin care composition can be added, together
with the laundry detergent or cleaning agent, in the drum or the
dispensing draw of a washing machine. This has the advantage that
no additional rinse cycle is required and that no unsightly
deposits appear in the dispensing draw. Moreover, this solid
composition is easier and better to handle than the liquid
compositions as no drops remain on the rim of the bottle, which
during subsequent storage of the bottle lead to marks underneath or
to unsightly deposits in the area of the closure. The same is true
for the case where some of the composition is accidentally spilled
when dosing it. As textile-softening clays also exhibit a
water-softening effect, additional deposits of lime scale onto the
washing are prevented.
[0011] Furthermore, it is advantageous that the textile-softening
clay and the textile and/or skin care compound are already directly
transported onto the washing at the start of the washing process,
such that they can develop their full potential.
[0012] The water-soluble carrier is preferably selected from the
group consisting of inorganic alkali metal salts, organic alkali
metal salts, inorganic alkaline earth metal salts, organic alkaline
earth metal salts, organic acids, carbohydrates, silicates, urea
and mixtures thereof.
[0013] These materials are not only inexpensive but dissolve very
well in water. Moreover, these materials are odorless.
[0014] The water-soluble carrier particularly preferably includes a
carbohydrate and is selected from the group consisting of dextrose,
fructose, galactose, isoglucose, glucose, saccharose, raffinose and
mixtures thereof.
[0015] When using a water-soluble carrier that consists of, or at
least predominantly consists of carbohydrates, the problem of
corrosion in the washing machine, which can occur particularly when
using inorganic salts as the water-soluble carrier, is
obviated.
[0016] The solid, textile and/or skin care composition
advantageously comprises 50 to 99 wt. %, preferably 75 to 95 wt. %
of the water-soluble carrier.
[0017] The solid, textile and/or skin care compound is particularly
preferably selected from the group consisting of textile-softening
polymers, fluorescence agents, anti-redeposition agents, optical
brighteners, graying inhibitors, shrink inhibitors, anti-creasing
agents, color transfer inhibitors, antimicrobials, germicides,
fungicides, antioxidants, antistats, ironing auxiliaries, UV
absorbers, water proofing agents, impregnation agents and mixtures
thereof.
[0018] Besides softness, a further advantageous effect will be
imparted to the textiles treated with the textile and/or skin care
composition according to the invention by adding one or more of
these textile and/or skin care compounds, or harmful or negative
effects that can occur during cleaning and/or conditioning and/or
wearing textile fabrics will be reduced, such as for example
fading, graying, skin irritations etc.
[0019] The textile and/or skin care composition quite particularly
preferably comprises a textile-softening polymer, preferably
selected from the group consisting of polysiloxanes, cationic
polymers and mixtures thereof.
[0020] By adding a textile-softening polymer, in particular a
polysiloxane, a cationic polymer or a mixture thereof, the
textile-softening effect of the textile and/or skin care
composition can be further increased.
[0021] Further, the textile and/or skin care composition preferably
comprises additional ingredients, preferably selected from the
group consisting of dyes, perfume, fillers, binders and mixtures
thereof. In a particularly preferred embodiment, the solid, textile
and/or skin care composition additionally comprises a perfume. In
this regard, it is particularly preferred that the quantity of
perfume ranges from 0.1 to 20 wt. %, preferably 1 to 10 wt. % and
particularly preferably 2 to 7 wt. %.
[0022] Textile and/or skin care compositions should most of all
also lend a pleasant fragrance to the washing, and for this reason
preferably comprise a perfume. The fragrant impression of the
washing can be enhanced by the optionally present polysiloxanes
and/or cationic polymers in the textile and/or skin care
composition. A further advantage of the textile and/or skin care
composition according to the invention, which is added in the main
wash cycle, is that already directly at the start of the washing
and cleaning process, the perfume is transported to the washing and
thus can develop its full potential.
[0023] Furthermore, for conventional liquid fabric softening
compositions containing quaternary ammonium compounds as the
textile-softener compound, a problem with the stability of the
composition also occurs at higher perfume concentrations (>0.4
wt. % perfume in regular fabric softening compositions and >1
wt. % in concentrated fabric softening compositions). Higher
amounts (>1 wt. %) of perfume can be incorporated without
difficulty in the textile and/or skin care compositions according
to the invention.
[0024] It is particularly preferred that the water-soluble carrier
is present in particulate form and is coated with a powder
including the softening clay and the textile and/or skin care
compound. In this context, the particle sizes of the water-soluble
carrier are particularly preferably in the range 0.6 to 30 mm,
particularly 0.8 to 7 mm and particularly preferably 1 to 3 mm.
[0025] This embodiment enables different textile and/or skin care
compositions to be easily and quickly comprised as only the
composition of the coating powder needs to be changed. The use of a
textile and/or skin care compound in the coating powder increases
the adhesion of the powder to the carrier. This is particularly the
case for liquid textile and/or skin care compounds. When using
textile-softening polymers, the softening power of the textile
and/or skin care composition can be further increased. This cannot
be achieved by a sole increase in the content of textile-softening
clay in the coating powder because as of a certain amount of
textile-softening clay in the coating powder, the latter will no
longer adhere sufficiently to the water-soluble carrier.
[0026] Textile and/or skin care compositions with particle sizes in
the range 0.8 to 7 mm and particularly preferably in the range 1 to
3 mm can be dosed particularly well and in a controlled manner.
[0027] The invention also relates to the use of an inventive solid,
textile and/or skin care composition for conditioning textile
fabrics.
[0028] Moreover, the invention relates to a process for
manufacturing a solid, textile and/or skin care composition,
including a particulate water-soluble carrier, a textile-softening
clay and a textile and/or skin care compound, in which the
particulate carrier and the textile-softening clay are mixed in the
presence of the textile and/or skin care compound.
[0029] The invention further relates to a laundry detergent or
cleaning agent, including an inventive solid, textile and/or skin
care composition.
[0030] By incorporating the inventive textile and/or skin care
composition in a laundry detergent or cleaning agent, a softening
laundry detergent or cleaning agent ("2 in 1" laundry detergent or
cleaning agent) is provided to the consumer, who does not need to
dose two compositions. Furthermore, when adding a perfume to the
textile and/or skin care composition, the laundry detergent or
cleaning agent and the textile and/or skin care composition do not
have to be perfumed, rather only one of the two compositions,
preferably the textile and/or skin care composition. This not only
yields lower costs but it is also advantageous for consumers with
sensitive skin and/or allergies. In addition, it is advantageous
that laundry detergents or cleaning agents with different textile
and/or skin care effects are easily and quickly obtained, as only
the composition of the textile and/or skin care composition have to
be changed.
[0031] The invention is described below in more detail inter alia
by means of examples.
[0032] The solid, textile and/or skin care composition comprises a
water-soluble carrier, a textile-softening clay and a textile
and/or skin care compound as the essential ingredients.
[0033] The textile and/or skin care composition comprises a
textile-softening clay, such as for example a smectite clay.
Preferred smectite clays are Beidellite clays, Hectorite clays,
Laponite clays, montmorillonite clays, Nontronite clays, Saponite
clays, Sauconite clays and mixtures thereof. Montmorillonite clays
are the preferred softening clays. Bentonites comprise mainly
montmorillonites and can serve as the preferred source for the
textile-softening clay.
[0034] Suitable Bentonites are for example marketed under the trade
names Laundrosil.RTM. from Sud-Chemie or under the trade name
Detercal.RTM. from Laviosa.
[0035] The amount of textile-softening clay in the textile and/or
skin care composition is between 0.1 and 10 wt. % and is preferably
1 to 5 wt. %.
[0036] In addition to the textile-softening clay, the textile
and/or skin care composition comprises a textile and/or skin care
compound. This is preferably selected from the group consisting of
textile-softening polymers, fluorescence agents, anti-redeposition
agents, optical brighteners, graying inhibitors, shrink inhibitors,
anti-creasing agents, color transfer inhibitors, antimicrobials,
germicides, fungicides, antioxidants, antistats, ironing
auxiliaries, UV absorbers, water proofing agents, impregnation
agents and mixtures thereof. In this context, the textile and/or
skin care composition preferably comprises a textile-softening
polymer, in particular a polysiloxane and/or a cationic
polymer.
[0037] A preferred useable polysiloxane possesses at least the
following structural units
##STR00001##
with R.sup.1=independently of one another C.sub.1-C.sub.30 alkyl,
preferably C.sub.1-C.sub.4 alkyl, in particular methyl or ethyl,
n=1 to 5000, preferably 10 to 2500, in particular 100 to 1500.
[0038] It can be preferred that the polysiloxane also possesses the
following additional structural units:
##STR00002##
with R.sup.1.dbd.C.sub.1-30 alkyl, preferably C.sub.1-C.sub.4
alkyl, especially methyl or ethyl, Y=optionally substituted, linear
or branched C.sub.1-C.sub.20 alkylene, preferably
--(CH.sub.2).sub.m-- with m=1 to 16, preferably 1 to 8, in
particular 2 to 4, especially 3, R.sup.2, R.sup.3=independently of
one another H or optionally substituted, linear or branched
C.sub.1-C.sub.30 alkyl, preferably C.sub.1-C.sub.30 alkyl
substituted with amino groups, particularly preferably
--(CH.sub.2).sub.b--NH.sub.2 with b=1 to 10, most preferably b=2,
x=1 to 5000, preferably 10 to 2500, especially 100 to 1500.
[0039] If the polysiloxane only possesses the structural unit a)
with R.sup.1=methyl, then it is a polydimethylsiloxane.
Polydimethylpolysiloxanes are known as textile-care compounds.
[0040] Suitable polydimethysiloxanes include DC-200 (ex Dow
Corning), Baysilone.RTM. M 50, Baysilone.RTM. M 100, Baysilone.RTM.
M 350, Baysilone.RTM. M 500, Baysilone.RTM. M 1000, Baysilone.RTM.
M 1500, Baysilone.RTM. M 2000 or Baysilone.RTM. M 5000 (all ex GE
Bayer Silicones).
[0041] It can also be preferred that the polysiloxane comprises the
structural units a) and b). A particularly preferred polysiloxane
possesses the following structure:
(CH.sub.3).sub.3Si--[O--Si(CH.sub.3).sub.2].sub.n--[O--Si(CH.sub.3){(CH.-

wherein the sum of n+x is a number between 2 and 10 000.
[0042] Suitable polysiloxanes with the structural units a) and b)
are commercially available for example under the brand names
DC2-8663, DC2-8035, DC2-8203, DC05-7022 or DC2-8566 (all ex Dow
Corning). The commercially available products Dow Corning.RTM.
7224, Dow Corning.RTM. 929 Cationic Emulsion or Formasil 410 (GE

[0076] Here, the cationic polymers do not only imperatively possess
a textile-softening effect, but can also exhibit a skin care
effect.
[0077] A skin care compound is understood to mean a compound or a
mixture of compounds that is absorbed on the textile during contact
of a textile with the solid, textile and/or skin care composition,
and during contact of the textile with skin lends the skin an
advantage compared with a textile that was not treated with the
textile and/or skin care composition according to the invention.
This advantage can include for example the transfer of the skin
care compound from the textile onto the skin, a lower water
transfer from the skin to the textile or a lower friction between
the surface of the skin and the textile.
[0078] The skin care compound is preferably hydrophobic, can be
liquid or solid and must be compatible with the other ingredients
of the solid, textile and/or skin care composition. The skin care
compound can include for example [0079] a) waxes such as carnuba,
spermaceti, beeswax, lanolin, derivatives thereof as well as their
mixtures; [0080] b) plant extracts, for example vegetal oils such
as avocado oil, olive oil, palm oil, palm nut oil, rape seed oil,
linseed oil, soya oil, peanut oil, coriander oil, castor oil,
poppy-seed oil, coconut oil, pumpkin seed oil, wheat germ oil,
sesame oil, sunflower oil, almond oil, macadamia nut oil, apricot
nut oil, hazel nut oil, jojoba oil or canola oil, aloe vera,
camomile as well as their mixtures; [0081] c) higher fatty acids
such as lauric acid, myristic acid, palmitic acid, stearic acid,
behenic acid, oleic acid, linoleic acid, linolenic acid, isostearic
acid or polyunsaturated fatty acids; [0082] d) higher fatty
alcohols such as lauryl alcohol, cetyl alcohol, stearyl alcohol,
oleyl alcohol, behenyl alcohol or 2-hexadecanol, [0083] e) esters,
such as cetyl octanoate, lauryl lactate, myristyl lactate, cetyl
lactate, isopropyl myristate, myristyl myristate, isopropyl
palmitate, isopropyl adipate, butyl stearate, decyl oleate,
cholesterol isostearate, glycerol monostearate, glycerol
distearate, glycerol tristearate, alkyl lactates, alkyl citrates
and/or alkyl tartrates; [0084] f) hydrocarbons such as paraffins,
mineral oils, squalane or squalene; [0085] g) lipids; [0086] h)
vitamins such as vitamin A, C or E or vitamin alkyl esters; [0087]
i) phospholipids; [0088] j) sun protection agents such as octyl
methoxycinnamate and butyl methoxybenzoylmethane; [0089] k)
silicone oils such as linear or cyclic polydimethylsiloxanes,
amino, alkyl, alkylaryl or aryl-substituted silicone oils and
[0090] l) mixtures thereof.
[0091] Further suitable textile care compounds preferably include
fluorescence agents, anti-redeposition agents, optical brighteners,
graying inhibitors, shrink inhibitors, anti-creasing agents, color
transfer inhibitors, antimicrobials, germicides, fungicides,
antioxidants, antistats, ironing auxiliaries, UV absorbers, water
proofing agents, impregnation agents. Specific examples for these
textile care compounds are to be found in the description of the
laundry detergent or cleaning agent according to the invention and
can also be used in the solid, textile and/or skin care
composition.
[0092] The solid, textile and/or skin care composition can also
comprise mixtures of the cited compounds.
[0093] The amount of textile and/or skin care compound in the
textile and/or skin care composition is 0.1 to 10 wt. % and
preferably between 1 and 6 wt. %.
[0094] A further essential ingredient of the solid, textile and/or
skin care composition is the water-soluble carrier. This preferably
includes inorganic alkali metal salts such as for example sodium
chloride, potassium chloride, sodium sulfate, sodium carbonate,
potassium sulfate, potassium carbonate, sodium hydrogen carbonate,
potassium hydrogen carbonate or mixtures thereof, organic alkali
metal salts such as for example sodium acetate, potassium acetate,
sodium citrate, sodium tartrate or potassium sodium tartrate,
inorganic alkaline earth metal salts such as for example calcium
chloride or magnesium chloride, organic alkaline earth metal salts
such as for example calcium lactate, carbohydrates, organic acids
such as for example citric acid or tartaric acid, silicates such as
for example water glass, sodium silicate or potassium silicate,
urea as well as mixtures thereof. The water-soluble carrier can
include in particular a carbohydrate that is selected for example
from the group consisting of dextrose, fructose, galactose,
isoglucose, glucose, saccharose, raffinose and mixtures thereof.
The added carbohydrate can be for example candy sugar or coarse
sugar.
[0095] The water-soluble carrier can also comprise mixtures of the
cited materials.
[0096] Preferably, the particle sizes of the water-soluble carrier
are in the range 0.6 to 30 mm, particularly 0.8 to 7 mm and
particularly preferably 1 to 3 mm. The water-soluble carrier
particularly preferably includes saccharose crystals with a
particle size of 1 to 2 mm.
[0097] It is particularly advantageous when the textile and/or skin
care compound is added as a liquid, either in pure form or in the
form of a solution, an emulsion or a dispersion, in order to
increase the adhesion of the coating to the water-soluble
carrier.
[0098] The textile and/or skin care composition according to the
invention can optionally comprise further ingredients.
[0099] In order to enhance the esthetic impression of the textile
and/or skin care composition, it may be colored with appropriate
colorants. Preferred colorants, which are not difficult for the
expert to choose, have high storage stability, are not affected by
the other ingredients of the laundry detergent or cleaning agent or
by light and do not have any pronounced substantivity for textile
fibers, so as not to color them.
[0100] Furthermore, the textile and/or skin care composition can
comprise a perfume. It is even particularly preferred that the
textile and/or skin care composition comprises a perfume.
[0101] Suitable perfume oils or fragrances include individual
odoriferous compounds, for example synthetic products of the ester,
ether, aldehyde, ketone, alcohol and hydrocarbon type. However,
mixtures of various odoriferous substances, which together produce
an attractive fragrant note, are preferably used. Such perfume oils
can also comprise natural mixtures of odoriferous compounds, as are
available from vegetal sources.
[0102] Preferably, the quantity of perfume in the textile and/or
skin care composition ranges between 0.1 and 20 wt. %, particularly
preferably between 1 and 10 wt. % and quite particularly preferably
between 2 and 7 wt. %.
[0103] In addition, the textile and/or skin care composition can
comprise a filler, such as silica or salts. The salts can include
for example alkali or alkaline earth salts, such as for example
sodium sulfate. The amount of filler can range between 0.1 and 10
wt. % and preferably ranges from 1 to 5 wt. %.
[0104] In order to increase the gloss, the textile and/or skin care
composition can also comprise a pearlizer. Exemplary suitable
pearlizers are ethylene glycol mono- and -distearate (for example
Cutina.RTM. AGS from Cognis) as well as PEG-3-distearate.
[0105] The textile and/or skin care composition can also comprise a
binder. Suitable binders include for example polyethylene glycols,
meltable carbohydrates, polyesters, fatty acids, fatty acid soaps
or quaternized ammonium compounds.
[0106] For manufacturing the textile and/or skin care composition,
the coating powder, including the textile-softening clay and the
textile and/or skin care compound as well as optional colorants,
perfume, fillers and/or pearlizers, is deposited on the
water-soluble carrier in a mixer.
[0107] The textile and/or skin care composition is particularly
suitable for conditioning textile fabrics and for this it is
brought into contact, together with a conventional laundry
detergent or cleaning agent, with the textile fabrics in the (main)
wash cycle of a conventional washing and cleaning process.
[0108] The textile and/or skin care composition can be incorporated
into a laundry detergent or cleaning agent.
[0109] For this, a solid laundry detergent or cleaning agent is
mixed with 0.1 to 20 wt. %, preferably 1 to 10 wt. % of the textile
and/or skin care composition according to the invention.
[0110] In addition to the textile and/or skin care composition, the
laundry detergents or cleaning agents according to the invention
comprise surfactant(s), wherein anionic, non-ionic, cationic and/or
amphoteric surfactants can be employed. Mixtures of anionic and
non-ionic surfactants are preferred from the technical viewpoint.
The total surfactant content of a laundry detergent is preferably
below 40 wt. % and particularly preferably below 35 wt. %, based on
the total laundry detergent.
[0111] Preferred non-ionic surfactants are alkoxylated,
advantageously ethoxylated, particularly primary alcohols
preferably containing 8 to 18 carbon atoms and, on average, 1 to 12
moles of ethylene oxide (EO) per mole of alcohol, in which the
alcohol group may be linear or, preferably, methyl-branched in the
2-position or may contain e.g. linear and methyl-branched groups in
the form of the mixtures typically present in oxo alcohol groups.
In particular, however, alcohol ethoxylates with linear alcohol
groups of natural origin with 12 to 18 carbon atoms, e.g. from
coco-, palm-, tallow- or oleyl alcohol, and an average of 2 to 8 EO
per mole alcohol are preferred. Exemplary preferred ethoxylated
alcohols include C.sub.12-14 alcohols with 3 EO, 4EO or 7EO,
C.sub.9-11 alcohol with 7 EO, C.sub.13-15 alcohols with 3 EO, 5 EO,
7 EO or 8 EO, C.sub.12-18 alcohols with 3EO, 5EO or 7EO and
mixtures thereof, as well as mixtures of C.sub.12-14 alcohols with
3 EO and C.sub.12-18 alcohols with 7 EO. The cited degrees of
ethoxylation constitute statistically average values that can be a
whole or a fractional number for a specific product. Preferred
alcohol ethoxylates have a narrowed homolog distribution (narrow
range ethoxylates, NRE). In addition to these non-ionic
surfactants, fatty alcohols with more than 12 EO can also be used.
Examples of these are tallow fatty alcohol with 14 EO, 25 EO, 30 EO
or 40 EO. Also, non-ionic surfactants that comprise the EO and PO
groups together in the molecule are employable according to the
invention. Here, block copolymers with EO-PO blocks or PO-EO blocks
can be added, but also EO-PO-EO copolymers or PO-EO-PO copolymers.
Of course, mixed alkoxylated non-ionic surfactants can also be
used, in which EO- and PO-units are not in blocks but rather
distributed statistically. Such products can be obtained by the
simultaneous action of ethylene oxide and propylene oxide on fatty
alcohols.
[0112] Furthermore, as additional non-ionic surfactants, alkyl
glycosides that satisfy the general Formula RO(G).sub.x can be
added, where R means a primary linear or methyl-branched,
particularly 2-methyl-branched, aliphatic group containing 8 to 22
and preferably 12 to 18 carbon atoms and G stands for a glycose
unit containing 5 or 6 carbon atoms, preferably glucose. The degree
of oligomerization x, which defines the distribution of
monoglycosides and oligoglycosides, is any number between 1 and 10,
preferably between 1.2 and 1.4. Alkyl glycosides are known, mild
surfactants.
[0113] Another class of preferred non-ionic surfactants which may
be used, either as the sole non-ionic surfactant or in combination
with other non-ionic surfactants are alkoxylated, preferably
ethoxylated or ethoxylated and propoxylated fatty acid alkyl esters
preferably containing 1 to 4 carbon atoms in the alkyl chain, in
particular fatty acid methyl esters.
[0114] Non-ionic surfactants of the amine oxide type, for example
N-cocoalkyl-N,N-dimethylamine oxide and N-tallow
alkyl-N,N-dihydroxyethylamine oxide, and the fatty acid
alkanolamides may also be suitable. The quantity in which these
non-ionic surfactants are used is preferably no more than the
quantity in which the ethoxylated fatty alcohols are used and,
particularly no more than half that quantity.
[0115] Other suitable surfactants are polyhydroxyfatty acid amides
corresponding to the Formula (VII),
##STR00003##
[0116] in which RCO stands for an aliphatic acyl group with 6 to 22
carbon atoms, R.sup.1 for hydrogen, an alkyl or hydroxyalkyl group
with 1 to 4 carbon atoms and [Z] for a linear or branched
polyhydroxyalkyl group with 3 to 10 carbon atoms and 3 to 10
hydroxyl groups. The polyhydroxyfatty acid amides are known
substances, which may normally be obtained by reductive amination
of a reducing sugar with ammonia, an alkylamine or an alkanolamine
and subsequent acylation with a fatty acid, a fatty acid alkyl
ester or a fatty acid chloride.
[0117] The group of polyhydroxyfatty acid amides also includes
compounds corresponding to the Formula (VIII),
##STR00004##
in which R stands for a linear or branched alkyl or alkenyl group
containing 7 to 12 carbon atoms, R.sup.1 for a linear, branched or
cyclic alkyl group or an aryl group containing 2 to 8 carbon atoms
and R.sup.2 for a linear, branched or cyclic alkyl group or an aryl
group or an oxyalkyl group containing 1 to 8 carbon atoms,
C.sub.1-4 alkyl or phenyl groups being preferred, and [Z] is a
linear polyhydroxyalkyl group, of which the alkyl chain is
substituted by at least two hydroxyl groups, or alkoxylated,
preferably ethoxylated or propoxylated derivatives of that
group.
[0118] [Z] is preferably obtained by reductive amination of a
sugar, for example glucose, fructose, maltose, lactose, galactose,
mannose or xylose. The N-alkoxy- or N-aryloxy-substituted compounds
may then be converted into the required polyhydroxyfatty acid
amides by reaction with fatty acid methyl esters in the presence of
an alkoxide as catalyst.
[0119] The content of non-ionic surfactants in the laundry
detergents or cleaning compositions is preferably 5 to 30 wt. %,
advantageously 7 to 20 wt. % and particularly 9 to 15 wt. %, in
each case based on the total laundry detergent or cleaning
agent.
[0120] Exemplary suitable anionic surfactants are those of the
sulfonate and sulfate type. Suitable surfactants of the sulfonate
type are, advantageously C.sub.9-13 alkylbenzene sulfonates, olefin
sulfonates, i.e. mixtures of alkene- and hydroxyalkane sulfonates
and disulfonates, as are obtained, for example, from C.sub.12-18
monoolefins having a terminal or internal double bond, by
sulfonation with gaseous sulfur trioxide and subsequent alkaline or
acidic hydrolysis of the sulfonation products. Those alkane
sulfonates, obtained from C.sub.12-18 alkanes by sulfochlorination
or sulfoxidation, for example, with subsequent hydrolysis or
neutralization, are also suitable. The esters of .alpha.-sulfofatty
acids (ester sulfonates), e.g. the .alpha.-sulfonated methyl esters
of hydrogenated coco-, palm nut- or tallow acids are likewise
suitable.
[0121] Further suitable anionic surfactants are sulfated fatty acid
esters of glycerine. They include the mono-, di- and triesters and
also mixtures of them, such as those obtained by the esterification
of a monoglycerine with 1 to 3 moles fatty acid or the
transesterification of triglycerides with 0.3 to 2 moles glycerine.
Preferred sulfated fatty acid esters of glycerol in this case are
the sulfated products of saturated fatty acids with 6 to 22 carbon
atoms, for example caproic acid, caprylic acid, capric acid,
myristic acid, lauric acid, palmitic acid, stearic acid or behenic
acid.
[0122] Preferred alk(en)yl sulfates are the alkali metal and
especially sodium salts of the sulfuric acid half-esters derived
from the C.sub.12-C.sub.18 fatty alcohols, for example from coconut
butter alcohol, tallow alcohol, lauryl, myristyl, cetyl or stearyl
alcohol or from C.sub.10-C.sub.20 oxo alcohols and those
half-esters of secondary alcohols of these chain lengths.
Additionally preferred are alk(en)yl sulfates of the said chain
lengths, which contain a synthetic, straight-chained alkyl group
produced on a petrochemical basis and which show similar
degradation behavior to the suitable compounds based on fat
chemical raw materials. The C.sub.12-C.sub.16 alkyl sulfates and
C.sub.12-C.sub.15 alkyl sulfates and C.sub.14-C.sub.15 alkyl
sulfates are preferred on the grounds of laundry performance. 2,3
alkyl sulfates, which can be obtained from Shell Oil Company under
the trade name DAN.RTM., are also suitable anionic surfactants.
[0123] Sulfuric acid mono-esters derived from straight-chained or
branched C.sub.7-21 alcohols ethoxylated with 1 to 6 moles ethylene
oxide are also suitable, for example 2-methyl-branched alcohols
with an average of 3.5 mole ethylene oxide (EO) or C.sub.12-18
fatty alcohols with 1 to 4 EO. Due to their high foaming
performance, they are only used in fairly small quantities in
cleaning compositions, for example in amounts of 1 to 5% by
weight.
[0124] Other suitable anionic surfactants are the salts of
alkylsulfosuccinic acid, which are also referred to as
sulfosuccinates or esters of sulfosuccinic acid and the monoesters
and/or di-esters of sulfosuccinic acid with alcohols, preferably
fatty alcohols and especially ethoxylated fatty alcohols. Preferred
sulfosuccinates comprise C.sub.8-18 fatty alcohol groups or
mixtures of them. Especially preferred sulfosuccinates contain a
fatty alcohol group derived from the ethoxylated fatty alcohols
that are under consideration as non-ionic surfactants. Once again
the particularly preferred sulfosuccinates are those, whose fatty
alcohol groups are derived from ethoxylated fatty alcohols with
narrow range homolog distribution. It is also possible to use
alk(en)ylsuccinic acids with preferably 8 to 18 carbon atoms in the
alk(en)yl chain, or salts thereof.
[0125] Particularly preferred anionic surfactants are soaps.
Saturated and unsaturated fatty acid soaps are suitable, such as
the salts of lauric acid, myristic acid, palmitic acid, stearic
acid, (hydrogenated) erucic acid and behenic acid, and especially
soap mixtures derived from natural fatty acids such as coconut oil
fatty acid, palm kernel oil fatty acid, olive oil fatty acid or
tallow fatty acid.
[0126] Anionic surfactants, including soaps may be in the form of
their sodium, potassium or ammonium salts or as soluble salts of
organic bases, such as mono-, di- or triethanolamine. Preferably,
the anionic surfactants are in the form of their sodium or
potassium salts, especially in the form of the sodium salts.
[0127] The content of anionic surfactants in the preferred laundry
detergents or cleaning compositions is 2 to 30 wt. %,
advantageously 4 to 25 wt. % and particularly 5 to 22 wt. %, in
each case based on the total laundry detergent or cleaning
agent.
[0128] In addition to the textile and/or skin care composition and
the surfactants, the laundry detergents and cleaning agents can
comprise additional ingredients that further improve the
application technological and/or esthetic properties of the laundry
detergents or cleaning agents. In the context of the present
invention, preferred laundry detergents or cleaning agents comprise
one or a plurality of materials from the group of builders,
bleaches, bleach activators, enzymes, fragrances, perfume carriers,
fluorescence agents, dyes, foam inhibitors, silicone oils,
anti-redeposition agents, optical brighteners, graying inhibitors,
shrink preventers, anti-crease agents, color transfer inhibitors,
antimicrobials, germicides, fungicides, antioxidants,
preservatives, corrosion inhibitors, antistats, bitters, ironing
aids, water-repellents and impregnation agents, swelling and
non-skid agents, neutral filler salts and UV-absorbers.
[0129] Silicates, aluminum silicates (particularly zeolites),
carbonates, salts of organic di- and polycarboxylic acids as well
as mixtures of these materials can be particularly cited as
builders that are comprised in the laundry detergents or cleaning
agents.
[0130] Suitable crystalline, layered sodium silicates correspond to
the general formula NaMSi.sub.xO.sub.2x+1 H.sub.2O, wherein M is
sodium or hydrogen, x is a number from 1.9 to 4 and y is a number
from 0 to 20, preferred values for x being 2, 3 or 4. Preferred
crystalline layered silicates of the given formula are those in
which M stands for sodium and x assumes the values 2 or 3. In
particular, both .beta.- and .delta.-sodium disilicates
Na.sub.2Si.sub.2O.sub.5. yH.sub.2O are preferred.
[0131] Other useful builders are amorphous sodium silicates with a
modulus (Na.sub.2O:SiO.sub.2 ratio) of 1:2 to 1:3.3, preferably 1:2
to 1:2.8 and more preferably 1:2 to 1:2.6, which dissolve with a
delay and exhibit multiple wash cycle properties. The delay in
dissolution compared with conventional amorphous sodium silicates
can have been obtained in various ways, for example by surface
treatment, compounding, compressing/compacting or by over-drying.
In the context of this invention, the term "amorphous" also means
"X-ray amorphous". In other words, the silicates do not produce any
of the sharp X-ray reflections typical of crystalline substances,
but at best one or more maxima of the scattered X-radiation, which
have a width of several degrees of the diffraction angle. However,
particularly good builder properties may even be achieved where the
silicate particles produce indistinct or even sharp diffraction
maxima in electron diffraction experiments. This can be interpreted
to mean that the products have microcrystalline regions between 10
and a few hundred nm in size, values of up to at most 50 nm and
especially up to at most 20 nm being preferred. Compacted/densified
amorphous silicates, compounded amorphous silicates and over dried
X-ray amorphous silicates are particularly preferred.
[0132] Of the suitable fine crystalline, synthetic zeolites
containing bound water, zeolite A and/or P are preferred. Zeolite
MAP.RTM. (commercial product of the Crosfield company), is
particularly preferred as the zeolite P. However, zeolite X and
mixtures of A, X and/or P are also suitable. Commercially available
and preferably used in the context of the present invention is, for
example, also a co-crystallizate of zeolite X and zeolite A (ca. 80
wt. % zeolite X), which is marketed by the SASOL Company under the
trade name VEGOBOND AX.RTM. and which can be described by the
Formula
nNa.sub.2O(1-n)K.sub.2OAl.sub.2O.sub.3(2-2.5)SiO.sub.2(3.5-5.5)H.sub.2O
n=0.90-1.0
[0133] The zeolite can be employed as the spray-dried powder or
also as the non-dried, still moist from its manufacture, stabilized
suspension. For the case where the zeolite is added as a
suspension, this can comprise small amounts of non-ionic
surfactants as stabilizers, for example 1 to 3 wt. %, based on the
zeolite, of ethoxylated C.sub.12-C.sub.18 fatty alcohols with 2 to
5 ethylene oxide groups, C.sub.12-C.sub.14 fatty alcohols with 4 to
5 ethylene oxide groups or ethoxylated isotridecanols. Suitable
zeolites have a mean particle size of less than 10 .mu.m (volume
distribution, as measured by the Coulter Counter Method) and
contain preferably 18 to 22% by weight and more preferably 20 to
22% by weight of bound water.
[0134] Naturally, the generally known phosphates can also be added
as builders, in so far that their use should not be avoided on
ecological grounds. The sodium salts of the orthophosphates, the
pyrophosphates and especially the tripolyphosphates are
particularly suitable.
[0135] Organic builders that can be present in the laundry
detergent or cleaning agent include polycarboxylate polymers such
as polyacrylates and acrylic acid/maleic acid copolymers,
polyaspartates and monomeric polycarboxylates such as citrates,
gluconates, succinates or malonates, which are preferably added as
the sodium salts.
[0136] Among the compounds, which serve as bleaching agents and
liberate H.sub.2O.sub.2 in water, sodium perborate tetrahydrate and
sodium perborate monohydrate are of particular importance. Examples
of additional bleaching agents that may be employed are sodium
percarbonate, peroxypyrophosphates, citrate perhydrates and
H.sub.2O.sub.2-liberating peracidic salts or peracids, such as
perbenzoates, peroxyphthalates, diperoxyazelaic acid, phthaloimino
peracid or diperoxydodecanedioic acid.
[0137] The laundry detergents or cleaning compositions can comprise
bleach activators in order to achieve an improved bleaching action
for washing temperatures of 60.degree. C. and below. Bleach
activators, which can be used, are compounds which, under
perhydrolysis conditions, yield aliphatic peroxycarboxylic acids
having preferably 1 to 10 carbon atoms, in particular 2 to 4 carbon
atoms, and/or optionally substituted perbenzoic acid. Substances,
which carry O-acyl and/or N-acyl groups of said number of carbon
atoms and/or optionally substituted benzoyl groups, are suitable.
Preference is given to polyacylated alkylenediamines, in particular
tetraacetyl ethylenediamine (TAED), acylated triazine derivatives,
in particular 1,5-diacetyl-2,4-dioxohexahydro-1,3,5-triazine
(DADHT), acylated glycolurils, in particular tetraacetyl glycoluril
(TAGU), N-acylimides, in particular N-nonanoyl succinimide (NOSI),
acylated phenolsulfonates, in particular n-nonanoyl- or
isononanoyloxybenzene sulfonate (n- or iso-NOBS), carboxylic acid
anhydrides, in particular phthalic anhydride, acylated polyhydric
alcohols, in particular triacetin, ethylene glycol diacetate and
2,5-diacetoxy-2,5-dihydrofuran.
[0138] In addition to, or instead of the conventional bleach
activators, so-called bleach catalysts may also be incorporated
into the laundry detergents or cleaning agents. These substances
are bleach-boosting transition metal salts or transition metal
complexes such as, for example, manganese-, iron-, cobalt-,
ruthenium- or molybdenum-salen or -carbonyl complexes. Manganese,
iron, cobalt, ruthenium, molybdenum, titanium, vanadium and copper
complexes with nitrogen-containing tripod ligands and cobalt-,
iron-, copper- and ruthenium-ammine complexes may also be used as
bleach catalysts.
[0139] The laundry detergent or cleaning agent can comprise
encapsulated enzymes and/or enzymes directly in the laundry
detergent or cleaning agent. Suitable enzymes are, in particular,
those from the classes of hydrolases, such as proteases, esterases,
lipases or lipolytic enzymes, amylases, cellulases or other
glycosyl hydrolases, hemicellulases, cutinases, .beta.-glucanases,
oxidases, peroxidases, perhydrolases and/or laccases and mixtures
of the cited enzymes. In the wash, all these hydrolases contribute
to the removal of stains such as protein, fat or starchy stains and
against graying. Moreover, cellulases and other glycosyl hydrolases
can contribute to increased softness of the textile and to color
retention by removing pilling and micro fibrils. Oxireductases can
also be added for bleaching or for reducing color transfer.
Enzymatic active materials obtained from bacterial sources or fungi
such as bacillus subtilis, bacillus licheniformis, streptomyceus
griseus and humicola insolens are particularly well suited.
Proteases of the subtilisin type and particularly proteases that
are obtained from bacillus lentus, are preferably used. Here,
mixtures of enzymes are of particular interest, for example
proteases and amylases or proteases and lipases or lipolytic
enzymes or proteases and cellulases or cellulases and lipases or
lipolytic enzymes or proteases, amylases and lipases or lipolytic
enzymes or proteases, lipases or lipolytic enzymes and cellulases,
in particular, however proteases and/or lipase-containing mixtures
or mixtures with lipolytic enzymes. Examples of such lipolytic
enzymes are the known cutinases. Peroxidases or oxidases have also
proved to be suitable in certain cases. The suitable amylases
particularly include .alpha.-amylases, iso-amylases, pullulanases
and pectinases. Cellobiohydrolases, endoglucanases and
.beta.-glucosidases, which are also known as cellobiases, or
mixtures thereof, are preferred cellulases. As the different
cellulase types differ in their CMCase- and avicelase activities,
the required activities can be adjusted by means of controlled
mixtures of the cellulases.
[0140] The enzymes can be adsorbed on carriers in order to protect
them against premature decomposition. The content of the enzymes,
enzyme mixtures or enzyme granules directly in the laundry
detergent or cleaning agent can be, for example, about 0.01 to 5%
by weight and is preferably 0.12 to about 2.5% by weight.
[0141] However, for example for specific laundry detergents or
cleaning agents for consumers with allergies and/or sensitive skin,
it can also be preferred that the laundry detergent or cleaning
agent does not comprise enzymes.
[0142] In one embodiment, the laundry detergent or cleaning agent
optionally comprises one or a plurality of perfumes, normally in an
amount of up to 10 wt. %, preferably 0.5 to 7 wt. %, particularly 1
to 3 wt. %. Here, the amount of added perfume also depends on the
type of the laundry detergent or cleaning agent. However, it is
particularly preferred that the perfume is incorporated into the
laundry detergent or cleaning agent through the textile and/or skin
care composition. However, it is also possible that the laundry
detergent or cleaning agent comprises perfume that has not been
incorporated into the laundry detergent or cleaning agent through
the textile and/or skin care composition.
[0143] In order to enhance the esthetic impression of the laundry
detergent or cleaning agent, they can be colored (also optionally
only partially) with appropriate colorants. Preferred colorants,
which are not difficult for the expert to choose, have high storage
stability, are not affected by the other ingredients of the laundry
detergent or cleaning agent or by light and do not have any
pronounced substantivity for textile fibers, so as not to color
them.
[0144] Soaps, paraffins or silicone oils, optionally deposited on
carrier materials, are examples of foam inhibitors that can be
incorporated into the laundry detergents or cleaning agents.
[0145] Suitable anti-redeposition agents, also referred to as soil
repellents, are for example non-ionic cellulose ethers such as
methyl cellulose and methyl hydroxypropyl cellulose with a content
of methoxy groups of 15 to 30 wt. % and hydroxypropyl groups of 1
to 15 wt. %, each based on the non-ionic cellulose ether, as well
as polymers of phthalic acid and/or terephthalic acid or their
derivatives known from the prior art, particularly polymers of
ethylene terephthalates and/or polyethylene and/or polypropylene
glycol terephthalates or anionically and/or non-ionically modified
derivatives thereof. Suitable derivatives include the sulfonated
derivatives of the phthalic acid polymers and the terephthalic acid
polymers. Modified, for example alkoxylated and/or quaternized
and/or oxidized polyamines represent a further class of suitable
soil release polymers, particularly for cotton-containing textiles.
The polyamines are for example polyalkyleneamines, such as
polyethyleneamines, or polyalkyleneimines, such as
polyethyleneimines. Preferred examples of this class of soil
release polymers are ethoxylated polyethyleneimines and ethoxylated
polyethyleneamines.
[0146] Optical brighteners (so called "whiteners") can be added to
the laundry detergents or cleaning agents in order to eliminate
graying and yellowing of the treated textile fabrics. These
materials absorb onto the fiber and effect a brightening and pseudo
bleach effect in that the invisible ultraviolet radiation is
converted into visible radiation, wherein the ultraviolet light
absorbed from sunlight is irradiated away as weak blue fluorescence
and results in pure white for the yellow shade of the grayed or
yellowed washing. Suitable compounds derive for example from the
substance classes of 4,4'-diamino-2,2'-stilbenedisulfonic acids
(flavonic acids), 4,4'-distyrylbiphenylene, methylumbelliferone,
coumarone, dihydroquinolinones, 1,3-diarylpyrazolines, naphthoic
acid imides, benzoxazole-, benzisoxazole- and benzimidazole-systems
as well as heterocyclic substituted pyrene derivatives. The optical
brighteners are usually added in amounts between 0% and 0.3 wt. %,
based on the finished laundry detergent or cleaning agent.
[0147] Graying inhibitors have the function of maintaining the dirt
that was removed from the fibers suspended in the washing liquor,
thereby preventing the dirt from resettling. Water-soluble colloids
of mostly organic nature are suitable for this, for example glue,
gelatines, salts of ether sulfonic acids of starches or celluloses,
or salts of acidic sulfuric acid esters of celluloses or starches.
Water-soluble, acid group-containing polyamides are also suitable
for this purpose. In addition, soluble starch preparations and
others can be used as the abovementioned starch products, for
example degraded starches, aldehyde starches etc. Polyvinyl
pyrrolidone can also be used. Preference, however, is given to the
use of cellulose ethers such as carboxymethyl cellulose (Na salt),
methyl cellulose, hydroxyalkyl cellulose and mixed ethers such as
methyl hydroxyethyl cellulose, methyl hydroxypropyl cellulose,
methyl carboxymethyl cellulose and mixtures thereof, which can be
added, for example in amounts of 0.1 to 5 wt. %, based on the
laundry detergent or cleaning agent.
[0148] In order to efficiently repress color dissolution and/or the
color transfer to other textiles during washing and/or cleaning of
colored textiles, the laundry detergent or cleaning agent can
comprise a color transfer inhibitor. The color transfer inhibitor
is preferably a polymer or copolymer of cyclic amines such as for
example vinyl pyrrolidone and/or vinylimidazole. As color transfer
inhibitors, suitable polymers include polyvinyl pyrrolidone (PVP),
polyvinylimidazole (PVI), copolymers of vinyl pyrrolidone and
vinylimidazole (PVP/PVI), polyvinylpyridine-N-oxide,
poly-N-carboxymethyl-4-vinylpyridium chloride as well as mixtures
of them. Polyvinyl pyrrolidone (PVP), polyvinylimidazole (PVI) or
copolymers of vinyl pyrrolidone and vinylimidazole (PVP/PVI) are
particularly preferably employed as color transfer inhibitors. The
added polyvinyl pyrrolidones (PVP) preferably have an average
molecular weight of 2 500 to 400 000 and are commercially available
from ISP Chemicals as PVP K 15, PVP K 30, PVP K 60 or PVP K 90 or
from BASF as Sokalan.RTM. HP 50 or Sokalan.RTM. HP 53. The added
copolymers of vinyl pyrrolidone and vinylimidazole (PVP/PVI)
preferably have a molecular weight in the range 5000 to 100 000. A
commercially available PVP/PVI copolymer is for example
Sokalan.RTM. HP 56 from BASF.
[0149] The amount of color transfer inhibitor based on the total
weight of the laundry detergent or cleaning agent is preferably
0.01 to 2 wt. %, advantageously from 0.005 to 1 wt. % and more
preferably from 0.1 to 0.5 wt. %.
[0150] Alternatively however, enzymatic systems, which include a
peroxidase and hydrogen peroxide or a substance that generates
hydrogen peroxide in water, can also be added as the color transfer
inhibitor. The addition of a mediator compound for the peroxidase,
for example, an acetosyringone, a phenol derivative or a
phenothiazine or phenoxazine is preferred in this case, wherein in
addition, the above-mentioned polymeric color transfer inhibitors
can also be used.
[0151] As textile fabrics, particularly of rayon, spun rayon,
cotton and their mixtures tend to crease because the individual
fibers are sensitive to flection, bending, pressing and squeezing
at right angles to the fiber direction, the laundry detergents or
cleaning agents can comprise synthetic anti-crease agents. They
include for example synthetic products based on fatty acids, fatty
acid esters, fatty acid amides, fatty acid alkylol esters, fatty
acid alkylol amides or fatty alcohols that have been mainly treated
with ethylene oxide, or products based on lecithin or modified
phosphoric acid esters.
[0152] The laundry detergents or cleaning agents can comprise
antimicrobial agents to control microorganisms. Depending on the
antimicrobial spectrum and the action mechanism, antimicrobial
agents are differentiated as bacteriostatic agents and
bactericides, fungistatic agents and fungicides, etc. Important
representatives of these groups are, for example, benzalkonium
chlorides, alkylaryl sulfonates, halophenols and phenol mercuric
acetate, wherein these compounds can also be totally dispensed with
in the inventive laundry detergents or cleaning agents.
[0153] The inventive laundry detergents or cleaning agents can
comprise preservatives, wherein preferably only those are used,
which have no or only a slight skin sensitizing potential. Examples
are sorbic acid and its salts, benzoic acid and its salts,
salicylic acid and its salts, phenoxyethanol,
3-iodo-2-propynylbutyl carbamate, sodium
N-(hydroxymethyl)glycinate, biphenyl-2-ol as well as mixtures
thereof. A suitable preservative is illustrated by the
solvent-free, aqueous combination of diazolidinyl urea, sodium
benzoate and potassium sorbates (obtainable as Euxyl.RTM. K 500 ex
Schuelke & Mayr), which can be employed in a pH range up to
7.
[0154] The agents can comprise antioxidants in order to prevent
undesirable changes caused by oxygen and other oxidative processes
to the laundry detergents or cleaning agents and/or the treated
textile fabrics. This class of compounds includes, for example,
substituted phenols, hydroquinones, pyrocatechols and aromatic
amines as well as organic sulfides, polysulfides, dithiocarbamates,
phosphites, phosphonates and vitamin E.
[0155] An increased wear comfort can result from the additional use
of antistats that can be included in the laundry detergents or
cleaning agents. Antistats increase the surface conductivity and
thereby allow an improved discharge of built-up charges. Generally,
external antistats are substances with at least one hydrophilic
molecule ligand and provide a more or less hygroscopic film on the
surfaces. These mainly interface active antistats can be subdivided
into nitrogen-containing (amines, amides, quaternary ammonium
compounds), phosphorus-containing (phosphoric acid esters) and
sulfur-containing (alkyl sulfonates, alkyl sulfates) antistats.
Lauryl (or stearyl) dimethyl benzyl ammonium chlorides are suitable
antistats for textile fabrics or as additives to laundry detergents
or cleaning agents, resulting in an additional finishing
effect.
[0156] Silicone derivatives, for example, can be incorporated in
the laundry detergents or cleaning agent to improve the
re-wettability of the treated textile fabrics and to facilitate
ironing of the treated textile fabrics. By their foam-inhibiting
properties, they additionally improve the final rinse behavior of
the laundry detergents or cleaning agents. Exemplary preferred
silicone derivatives are polydialkylsiloxanes or
alkylarylsiloxanes, in which the alkyl groups possess one to five
carbon atoms and are totally or partially fluorinated. Preferred
silicones are polydimethylsiloxanes that can be optionally
derivatized and then are aminofunctional or quaternized or possess
Si--OH, Si--H and/or SiCl bonds. The viscosities of the preferred
silicones at 25.degree. C. are in the range between 100 and 100 000
mPas, wherein the silicones can be added in amounts between 0.2 and
5 wt. % based on the total laundry detergent or cleaning agent.
[0157] Finally, the laundry detergents or cleaning agents can also
comprise UV absorbers that are absorbed on the treated textile
fabrics and improve the light stability of the fibers. Compounds,
which possess these desired properties, are for example, the
efficient radiationless deactivating compounds and derivatives of
benzophenone having substituents in position(s) 2-and/or 4. Also
suitable are substituted benzotriazoles, acrylates, which are
phenyl-substituted in position 3 (cinnamic acid derivatives),
optionally with cyano groups in position 2, salicylates, organic Ni
complexes, as well as natural substances such as umbelliferone and
the endogenous urocanic acid.
[0158] Substances can be added to complex heavy metals in order to
prevent heavy metal catalyzed decomposition of certain detergent
ingredients. Suitable heavy metal sequestrants are, for example,
the alkali salts of ethylene diamine tetra acetic acid (EDTA) or of
nitrilotriacetic acid (NTA) as well as alkali metal salts of
anionic polyelectrolytes such as polyacrylates, polymaleates and
polysulfonates.
[0159] A preferred class of sequestrants are the phosphonates that
are comprised in the preferred laundry detergents or cleaning
agents in amounts of 0.01 to 2.5 wt. %, preferably 0.02 to 2 wt. %
and particularly 0.03 to 1.5 wt. %. These preferred compounds
particularly include organophosphonates such as for example
1-hydroxyethane-1,1-diphosphonic acid (HEDP),
aminotri(methylenephosphonic acid) (ATMP), diethylenetriamine
penta(methylenephosphonic acid) (DTPMP or DETPMP) as well as
2-phosphonobutane-1,2,4-tricarboxylic acid (PBS-AM), which are
mainly added in the form of their ammonium or alkali metal
salts.
[0160] In addition, the solid laundry detergents or cleaning agents
can even comprise neutral filler salts such as sodium sulfate or
sodium carbonate.
[0161] The laundry detergents or cleaning agents according to the
invention can be particularly used for cleaning and conditioning
textile fabrics.
[0162] For manufacturing the laundry detergents or cleaning agents
according to the invention, the laundry detergent or cleaning agent
is first manufactured without the textile and/or skin care
composition using known methods that can include for example drying
steps, mixing steps, densification steps, molding steps and/or the
subsequent addition of heat-sensitive ingredients (post addition).
The resulting product is subsequently blended with a solid, textile
and/or skin care composition. For manufacturing molded bodies of
laundry detergents or cleaning agents, additional densification
and/or molding steps can follow the mixing step.
[0163] Inventive textile and/or skin care compositions E1 to E5 are
shown in Table 1.

[0164] In order to compare the fragrance intensity of a
conventional liquid fabric softener (textile-softening diesterquat
content of 15 wt. %) with those of the solid, textile and/or skin
care compositions E1 and E2, cloth toweling was treated on the one
hand with a solid, commercially available laundry detergent and the
conventional fabric softener, and on the other hand with the same
laundry detergent and respectively the solid textile and/or skin
care compositions E1 and E2 in a washing machine (Miele Novotronic
W985). After hanging up to dry, the fragrance intensity was
determined:

[0165] In addition, in comparison with water, the inventive textile
and/or skin care compositions showed a softening effect (after the
cloths had been treated with water or with the textile and/or skin
care compositions and had been hung up to dry, they were evaluated
by a panel of 5 people). In addition, the inventive textile and/or
skin care compositions are able to reduce the water hardness. This
measurement was carried out with "total hardness test" analysis
rods (ex Merck) following the manufacturer's instructions.
[0166] An inventive laundry detergent or cleaning agent was
manufactured by mixing a solid, unperfumed laundry detergent or
cleaning agent with 10 wt. % (based on the finished laundry
detergent or cleaning agent) of the textile and/or skin care
composition E6.
[0167] The inventive laundry detergent or cleaning agent showed
good cleaning and conditioning properties.
[0168] Lime scale deposits on the washing and/or deposits/residues
in the dispensing draw of the washing machine were not observed,
either for separate application of the textile and/or skin care
composition or when incorporated in a laundry detergent or cleaning
agent.
